Excelente!!
Melhor explicação de geomorphons que encontrei!
the best explanation on geomorphons that I found. Quick and complete.
It's been very useful to my students here in Uberaba, Minas Gerais, Brazil!

Very usefull film. In the source geomorphons publication (Jasiewicz & Stepinski 2013) is probably error in the equation (1) for DΔL (terrain Openness in particular Direction and Scale) or I didn't understand something. Hence my question:

In the DΔL calculations:
If the positive openess (Φ) is greater than the negative one (Ѱ) (central px is higher than every pixels on the direction line) DΔL = 1;
If the positive openess (Φ) is smaller than the negative one (Ѱ) (central px is lower than every pixel on the direction line) DΔL = 0; //why 0 and not -1?

And when the DΔL = "-1"? - when we have flat ground? In the equation it is apear some "b" element and it is disapear the "=" symbol.

Intuitively, it should be "-1" for pixels lower than the horizon, "0" for the same, and "1" for pixels higher than the horizon (as in 2.1. chapter of the publication). Can You explain me this problem?

Very Good explanation, keep it up and this channel will become famous in the coming future if you work hard to share your knowledge as possible as you can. Thank you for sharing your knowledge for now.
